Since the advent of extracorporeal membrane oxygenation (ECMO) over 40 years ago, there has been increasing interest in the use of the extracorporeal circuit as a platform for providing multiple organ support. In this review, we will examine the evidence for the use of continuous renal replacement therapy, therapeutic plasma exchange, leukopheresis, adsorptive therapies, and extracorporeal live...

An unusual ceria dispersion was achieved by using the confined space between template and silica walls in as-prepared mesoporous silica, for the first time. The new adsorbents exhibit high adsorptive desulfurization activity and, more importantly, excellent stability and reusability, which is impossible to realize with conventional adsorbents.

A n effective adsorbent for the ethylene/ethane separation has been prepared by the dispersion of CuCl in large NaX crystals. The results from the thermo gravimetric analysis (TGA) indicate a maximal dispersion capacity of 36 wt% of CuCl for the NaX crystals. Single component isotherms of ethane and ethylene on CuCl/NaX show that the CuCl containing adsorbents are highly favourable to the olefi...

Sulfoanted poly(ether ether ketone) membranes were prepared by the sulfonating agent sulfuric acid. These membranes were modifed by incorporating conducting polymer polypyrrole in order to increase the ionic conductivity and reduce the methanol transmission rate. The modifed composite membranes were then compared on the basis of ionic conductivity, methanol transmission...

The reduction mechanism of molybdenum-methyl thymol blue (MTB)-chlorate system has been investigated in water on a mercury electrode. As this system is very sensitive for ultratrace determination of molybdenum, the actual mechanism involved was studied. Electrochemical techniques, including dc tast polarography and cyclic voltammetry were employed. It is shown that, the cathodic wave of mol...

A novel synthetic route is designed, employing both high temperature and a nontoxic organic structure-directing agent (SDA), for the synthesis of high silica zeolite Y. The N-methylpyridinium used as an organic SDA is stable during the synthesis, and the high silica zeolite Y shows high hydrothermal stability and good catalytic performance, as well as excellent adsorptive properties.

We demonstrate active tuning of DNA adsorption on silica beads using an electrical switch in a microfluidic device; we use electrolysis of water to alter pH in a packed bed of silica beads and switch the silica bead surface between being adsorptive and desorptive for DNA molecules.

2-Methylisoborneol (MIB) and geosmin are naturally occurring compounds responsible for musty-earthy taste and odor in public drinking-water supplies, a severe problem faced by many utilities throughout the world. In this study, we investigated adsorptive removal of these compounds by superfine powdered activation carbon (SPAC, particle size <1 μm) produced by novel micro-grinding of powdered ac...
